Variations: Pedagogical Tools
Variations on Video Initial planning grant, Aug 2010 – Jan 2011 from the Institute of Museum and Library Services IU & Northwestern are lead institutions Funding multi-institutional collaboration on functional and technical requirements Goal: Submit full implementation grant proposal to IMLS in Feb 2011 Add online video access capabilities to Variations, providing equivalent access, annotation, and analysis tools to support teaching and learning.
Motivators for Variations on Video Demand from Variations implementers Increased video digitization locally at IU IU Media Preservation Initiative IU IT strategic plan: Empowering People History of involvement in open and community source software Desire to create a sustainable foundation for Variations development and maintenance
Variations on Video: Scope Access to managed collections Video, audio Focus on libraries, archives Research, teaching, and learning use Variety of access control requirements Integration with preservation repository services Ad-hoc faculty/student uploads Classroom capture Live streaming Working digital assets – media production
Variations on Video: Content Video digitized from library collections Files with purchased or licensed streaming rights University produced video Archival collections Faculty- produced video Feature Films Documentaries TV shows Live Performances Lecture Series Field Recordings Research- related Video
Variations on Video Grant Objectives Identify functional and technical requirements and define scope based on input from: Librarians and technologists Faculty and students Technical investigation and gap analysis Develop high-level technical architecture and development plan Form partnership for development and ongoing maintenance Submit IMLS National Leadership Grant proposal (February 2011)
SURVEY RESULTS Spring 2010
Overview Survey conducted online April 29 - June 5, 2010 Invitations sent to – MLA-L – Code4lib – Some Variations lists – DLF-L – SYSLIB-L – VIDEOLIB – AMIA-L Approximately 150 respondents completed the survey, though most questions were optional so response numbers vary Of these, ~90 reported currently streaming video
Primary Institutional Role Who were the survey respondents? (N = 136) Other: Media Specialists (3) Archivists (2) Digital Services Librarian (2) Programmer, Metadata Librarian, Faculty, Developer….
THOSE CURRENTLY STREAMING VIDEO ~90 respondents
What are the main kinds of video content you stream? Check all that apply (N=94)
What streaming server do you use? Check all that apply (N=88) Other: includes Wowza, YouTube, iTunes, VideoFurnace, Apple H.264 ….
What method do you use to restrict access to your streaming video? Check all that apply (N=91) Other: Some materials are open, some are not; on-campus only; it depends….
Which organization has primary responsibility for managing your video streaming server technology? (N=92) Library (47%) Campus IT Department (27%) Consortium of which we are a member (7%) A commercial third-party to whom we outsource (4%) Other (15%) – Most of these responses were multiple servers run by multiple organizations
What do you like about your current video streaming solution? (N=66) Reliability Broader/easier access Tools: Clips can be created by faculty for courses, videos can be embedded, access can be controlled at several levels by admin. Easy to use and set up High praise from faculty and students Video stream is high-quality Security and password protection Conversion of obsolete formats Support for a variety of formats (open responses categorized by topic, ranked highest to lowest by count)
What needs are not well met by your current solution? (N=57) Rights management Ability to control authentication or restrict access Lacking clip creation, Blackboard embed, clip portability, collaboration, bookmarking Workflow is time-consuming, labor-intensive Off-campus access, mobile access Metadata production Limited file support Platform limitations (only vendor products can be used) Statistical data gathering (open responses categorized by topic, ranked highest to lowest by count)
THOSE NOT CURRENTLY STREAMING VIDEO ~60 respondents
What statement best describes your library’s plans for streaming video? (N=66)
If you have already decided which video streaming server to use (or have a leading candidate), indicate which one you have chosen (N=24) Other: Wowza (2), Flash (2), RealMedia, CONTENTdm, Video Furnace, Kaltura, SAFARI Montage
What main types of video content would you like to stream? Check all that apply (N=64)
BOTH GROUPS OF RESPONDENTS ~150 respondents
What is important in a video streaming solution? Must Have Would Like Not Sure Don’t Need Users can adjust playback location precisely (within a second of the desired location) Users can mark a particular location in a video for future immediate access (bookmarking) Users can create a playlist of segments from different videos for future reference Videos can be accompanied by transcripts Video content can be delivered to mobile devices (The following selected answers show highest ‘must have’ responses)
What is important in a video streaming solution? Must Have Would Like Not Sure Don’t Need Video content can be integrated into a discussion forum or chat tool for group discussion Users can share textual annotations with other users Video content can be integrated into an online quiz/test tool Video marking, annotation, playlists, and segmenting can be accomplished on mobile devices (The following selected answers show highest ‘don’t need’ responses)
Interactive, end-user features wanted in a video streaming solution Clips can be downloaded for use in other applications Closed and Soft Captioning Search by indexed transcript Tools for creating learning objects for integration into online classes Re-purposing of content for student use (annotation, bookmarking, remixing) Remote Access Statistics on use (overall, by school, by staff member) (open responses categorized by topic, ranked highest to lowest by count)
Which of the following repositories or digital asset management systems are you currently running? Check all that apply (N=107) Other includes Digital Commons, bepress, DigiTool, Symposia, custom in-house systems….
If you are running a repository or digital asset management system, check any that you use to store video assets (N=68) Other: In-house or custom (6), bepress (2), Digital Commons (2), various….
Additional Comments Copyright barriers Cost of licensing No coherent policy on fair use in this ‘Wild West DRM frontier’ Conflicts between needs of Library and IT Storage costs Faculty and students love their streaming video solution Increased collaboration IssuesLikes & Opportunities (open responses categorized by topic, ranked highest to lowest by count)
Variations on Video Project Participant Meeting Held October 5-6, 2010, at IU Institutions contributed usage scenarios to surface user requirements Analyzed scenarios and developed functional & technical requirements
Variations on Video: Other Planning Phase Participants
Preliminary directions More likely to focus on ingest, management and delivery than on sophisticated analysis and annotation, at least initially Tending towards a modular approach Investigating opportunities to leverage work of other projects where possible, such as Opencast Matterhorn and Kaltura
Initial Module List (tentative) Ingest/transcoding Media delivery server Basic player interface Simple metadata storage and management search Access control (with or without rights), with authentication piece Ability to import metadata from other systems
Basic Player Navigational metadata (i.e., chapters/tracks) Precise, responsive time positioning Embeddable Browser and mobile support Transcripts and captioning Bookmarking Clip and playlist creation
